Letters Patent No. 114,334, dated May 2, 1871.

IMPROVEMENT lN PLOWS.

The Schedule referred to in these-Letters Patent and making part of thelame.

To all whom it may concern:

Be it known that I, W ILLIAM F. PARKER, of Troy, in the county of Pikeand State of Alabama, have invented a new and improved Plow; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being bad to the accompanying drawing making apart of this specification, in which- Figure 1 is a side elevation.

Figure 2 is a top view.

This invention relates to an improved arrangement of certain parts ordevices composing a cultivator of the class whose shares are verticallyadjustable, while their pitch or inclination to the planes of thesurface of the soil may be varied by a change in the position of thestandard.

The invention particularly consists in the arrangement of parts ashereinafter described, and as specifically stated in the claim.

Referring to the drawinga is a plow-beam.

b, an inclined standard secured to the rear end of the beam.

0, a metal stock forked at its upper extremity so as to embrace the beama between its prongs d.

a is a metal bar jointed at one end to the bottom of the stock 0 and atthe other end to the bottom of the I standard 1).

f is the plowshare, the same being secured to the front side of thestock 0 by means of a bolt, i, fastened at its head to the share, andextending from the latter into and through a slot made lengthwise of thestock 0, said bolt being threaded outside and combined with a nut, m,byscrewing which against the rear side of the stock 0 the share f isclamped against the latter.

By means of the slot the share may be moved up or down on the stock; butI do not allege any novelty in the slotted stock by itself. My stock ispeculiar in this, that it is notched on its front side, as shown at n.

The top of the share f should always be in-coutact with one or the otherof the shoulders n, by which arrangement the share is effectuallyprevented from being forced upward along the stock.

The prongs d of the stock 0 are connected by a bolt, g, which may bescrewed in or out as regards the prongs.

Into the top of the beam a is let a plate, 71-, the upper side of whichis transversely fluted in grooves k, which are of proper size to receivethe bolt g.

By loosening the bolt in the prongs it may be transferred from one ofthe grooves It to any one of the others, and there secured by screwingthe bolt in the back. This change of the bolt from one groove in toanother alters the pitch of the share. The connecting of the stock andbar 0 by a joint enables this change to be accomplished withoutdifficulty.

The lower end of the standard I) is protected from abrasion by a metalhood, 1.

Any kind of plowshare may be used.

\Vithont claiming as new any of the devices, per se,

whereof mycnltiva'tor is composed, I believe to be novel and desire toprotect by Letters Patent- The arrangement of the bar 0, forked stock 0jointed thereto and carrying the share or shovel f, and the groovedplate It and bolt g, with the rigid standard I) and beam (1, as hereinshown and described, for the purpose specified.

WILLIAM F. PARKER.
